SQL Server가 여러 레코드의 마지막 날짜를 검색합니다.

Question

5 개의 열이있는 테이블이 있습니다. Emp, Surname, CSD, Term Rsn 및 Date입니다. 처음 4 개의 열은 동일하게 유지되지만 날짜가 바뀝니다. 30 가지 날짜가있는 Emp에 대해 30 개의 레코드가있을 수 있습니다.

이

작동하는 내 코드입니다하지만 난 그게 내가 날짜 필드 사용을 선택하면 마지막 날짜

Create PROCEDURE testPro( 
@reportStartDate date, 
@reportEndDate date  
)  
AS 
BEGIN  


SELECT DISTINCT Emp, Surname, CSD, CASE WHEN CSD<= @reportStartDate 
THEN 

CASE WHEN [Term Rsn] != 0 THEN 
CASE WHEN [Date] <= @reportEndDate THEN 
(DATEDIFF(dd,@reportStartDate, [Date]) - (2* 
DATEDIFF(wk,@reportStartDate,[Date])))+1 ELSE (DATEDIFF(dd,@reportStartDate, @reportEndDate) - (2* 
DATEDIFF(wk,@reportStartDate,@reportEndDate)))+1 END ELSE (DATEDIFF(dd,@reportStartDate, @reportEndDate) - (2* 
DATEDIFF(wk,@reportStartDate,@reportEndDate)))+1 END 


ELSE 

CASE WHEN [Term Rsn] != 0 THEN 
CASE WHEN [Date] <= @reportEndDate THEN 
(DATEDIFF(dd,CSD, [Date]) - (2* 
DATEDIFF(wk,CSD,[Date])))+1 ELSE (DATEDIFF(dd,CSD, @reportEndDate) - (2* 
DATEDIFF(wk,CSD,@reportEndDate)))+1 END ELSE (DATEDIFF(dd,CSD, @reportEndDate) - (2* 
DATEDIFF(wk,CSD,@reportEndDate)))+1 END 

END AS [Working Days] 

FROM GyPremiumsTemp 
WHERE CSD < @reportEndDate AND [Date] > @reportStartDate --AND [Date] = (select max([Date]) FROM GyPremiumsTemp) 
ORDER BY Emp ASC 
END 


    EXEC testPro '2012-01-01', '2012-12-31'

쓰기 :

Create PROCEDURE testPro( 
@reportStartDate date, 
@reportEndDate date  
)  
AS 
BEGIN 
select Emp, Surname, CSD,[Working Days] , Max(Date) as [Date] 
From (
SELECT DISTINCT Emp, Surname, CSD, CASE WHEN CSD<= @reportStartDate 
THEN 

CASE WHEN [Term Rsn] != 0 THEN 
CASE WHEN [Date] <= @reportEndDate THEN 
(DATEDIFF(dd,@reportStartDate, [Date]) - (2* 
DATEDIFF(wk,@reportStartDate,[Date])))+1 
ELSE (DATEDIFF(dd,@reportStartDate, @reportEndDate) - (2* 
DATEDIFF(wk,@reportStartDate,@reportEndDate)))+1 END 
ELSE (DATEDIFF(dd,@reportStartDate, @reportEndDate) - (2* 
DATEDIFF(wk,@reportStartDate,@reportEndDate)))+1 END 


ELSE 

CASE WHEN [Term Rsn] != 0 THEN 
CASE WHEN [Date] <= @reportEndDate THEN 
(DATEDIFF(dd,CSD, [Date]) - (2* 
DATEDIFF(wk,CSD,[Date])))+1 
ELSE (DATEDIFF(dd,CSD, @reportEndDate) - (2* 
DATEDIFF(wk,CSD,@reportEndDate)))+1 END 
ELSE (DATEDIFF(dd,CSD, @reportEndDate) - (2* 
DATEDIFF(wk,CSD,@reportEndDate)))+1 END 

END AS [Working Days],[Date] -- Add all Dates here 

FROM GyPremiumsTemp 
WHERE CSD < @reportEndDate AND [Date] > @reportStartDate 
) T 
Group By Emp, Surname, CSD,[Working Days] 
ORDER BY Emp ASC 
END 


EXEC testPro '2012-01-01', '2012-12-31'

Answer 2

에 하나 개의 레코드를 반환하려고하는 반면 모든 30 개 레코드를 반환 선택에 [날짜]를 추가 할 때 : 아래 선택 최대 (일), EMP를, EMP를하여 테이블 그룹에서 성 , 성

This will give you one record per employee.I hope this helps.
